Airflow Configuration
Range for the airflow settings will depend on model and capacity selection (in 25 cfm increments).
Configuration Setting
Description
Min Heating Airflow
(applies to Trilogy units)
Configures the unit airflow while operating at minimum capacity in the heating mode. The installer may wish to select
a higher cfm than the nominal cfm for this setting to ensure proper air movement during low-capacity operation.
Max Heating Airflow
(applies to Trilogy units)
Configures the unit airflow while operating at maximum capacity in the heating mode. The installer may wish
to select a lower cfm than the nominal cfm for this setting to avoid air velocity noise from the ductwork during
maximum capacity operation.
Min Cooling Airflow
(applies to Trilogy units)
Configures the unit airflow while operating at minimum capacity in the cooling mode. The installer may wish to
select a higher cfm than the nominal 400 cfm/ton for this setting to ensure proper air movement during low-
capacity operation.
Max Cooling Airflow
(applies to Trilogy units)
Configures the unit airflow while operating at maximum capacity in the cooling mode. The installer may wish to
select a lower cfm than the nominal 400 cfm/ton for this setting to avoid air velocity noise from the ductwork during
maximum capacity operation.
Low Dehumidification Airflow
(applies to Trilogy units)
Configures the unit airflow while operating at minimum capacity in the dehumidification mode.
High Dehumidification Airflow
(applies to Trilogy units)
Configures the unit airflow while operating at maximum capacity in the dehumidification mode.
Heat Stage 1 Airflow
(applies to Tranquility units)
Configures the unit airflow while operating at minimum capacity in the heating mode. The installer may wish to select
a higher cfm than the nominal cfm for this setting to ensure proper air movement during low-capacity operation.
Heating Stage 2 Airflow
(applies to Tranquility units)
Configures the unit airflow while operating at maximum capacity in the heating mode. The installer may wish
to select a lower cfm than the nominal cfm for this setting to avoid air velocity noise from the ductwork during
maximum capacity operation.
Auxiliary Heat Airflow
(applies to Tranquility units)
Configures the unit airflow during the auxiliary heat mode (if applicable).
Emergency Heat Airflow
Configures the unit airflow during the emergency heat mode (if applicable).
Cool Stage 1 Airflow
(applies to Tranquility units)
Configures the unit airflow while operating at minimum capacity in the cooling mode. The installer may wish to
select a higher cfm than the nominal 400 cfm/ton for this setting to ensure proper air movement during low-
capacity operation.
Cooling Stage 2 Airflow
(applies to Tranquility units)
Configures the unit airflow while operating at maximum capacity in the cooling mode. The installer may wish to
select a lower cfm than the nominal 400 cfm/ton for this setting to avoid air velocity noise from the ductwork during
maximum capacity operation.
Cool Dehumidification Stage 1 Airflow
(applies to Tranquility units)
Configures the unit airflow while operating at minimum capacity in the dehumidification mode.
Cool Dehumidification Stage 2 Airflow
(applies to Tranquility units)
Configures the unit airflow while operating at maximum capacity in the dehumidification mode.
Constant Fan Airflow
Configures the unit airflow while operating in the continuous fan mode.
Heat Off Delay
This setting determines whether (and how long) the blower will continue to operate after the compressor has
cycled off at the end of each heating cycle (0 seconds to 255 seconds, in 5 second increments).
Cool Off Delay
This setting determines whether (and how long) the blower will continue to operate after the compressor has
cycled off at the end of each cooling cycle (0 seconds to 255 seconds, in 5 second increments).
Loop Configuration
Configures the internal vFlow device to the application. The vFlow device will adjust the flow to maintain the selected
temperature difference (Delta T) between the entering and leaving water for the active operating mode.

Variable Speed Pump
Loop Option
Configures the application for the loop.
Single system (one

Single system
Heating Delta T
Sets the source water flow rate for the heating mode. The variable speed pump
or motorized valve will adjust the source water flow to maintain the selected
temperature difference between the entering and leaving source water during
the heating mode.
5.0°F to 12.0°F
6.0°F
Cooling Delta T
Sets the source water flow rate for the cooling mode. The variable speed pump
or motorized valve will adjust the source water flow to maintain the selected
temperature difference between the entering and leaving source water during
the cooling mode.
9.0°F to 20.0°F
10.0°F
